T0 all 107mm t may concern:

Be it known that l, HENRY B. DALLIMORE, a citizen of the United States,and a resident of the city of Brooklyn, in the county of Kings and Stateof New York, have invented a new and lmproved Gas-Heater, of which thefollowing is a full, clear, and eX-' act description.

rFhis invention relates to improvements in gas heaters, and moreparticularly to a gas heater adapted to be positioned in the fire box ofan ordinary coal range, an object of the invention being to provide aheater of the character stated which will function as a heater for thewater back, as well as for the oven and stove ltop to permit the use ofthe range for all ordinary purposes dispensing with the necessity forusing coal.

A further object is to provide a device of the character stated whichcan be quickly and easily assembled in a fire boX, which dis penses withthe use of bolts and nuts to connect the parts, and which can be readilytaken apart, and damaged parts replaced with but relatively smallexpense.

With these and other objects in view, the' invention consists in certainnovel features of yconstruction and combinationsl and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims s In the accompanying drawings Figure 1 is a view mainly inelevation but partly in section illustrating my improved heater in thefire box of a coal range.

Fig. 2 is a view in section on the line 2 2 of Fig. 5. f

Fig. 3 is a fragmentary perspective view showing the manner ofconnecting the burner box to a standard.

Fig. t is a fragmentary sectional perspectiveview illustrating thedistributing screen and adjacent parts.

Fig. 5 is a view in front elevation of the burner partly in section.

Fig. 6 is a top plan view of Fig. 5.

Fig. 7 is a fragmentary sectional perspective view illustrating a damperattachment fol1 the burner box. y

1 represents an ordinary coal range, having a Afire box 2, the latterprovided with a water back 3 connected by water circulating pipes l and5 with a water tank or domestic boiler 6. f

ln positionincr my improved heater AV in the fire bor. .2, fdispensewith the ordinary grate of the range, and support the standards 7 of theheater directlyon the bottoni of the ash pit 8. y

The heater A is made'with a pair of relatively wiole open-work castmetal standards 7 supporting a top casting and a burner box 10 below thesame. The top casting 9 is made with depending slotted lugs 11 receivingwedges 12, the latter projected through the standards 7 and effectuallysecuring the parts together.

The box 10 is made at its ends with slotted lugs 13 which are projectedthrough suitable slots 14 in the standards and vsecured by means ofwedges 15. i

A coupling block 16 is secured to one standard 7 by means of a wedge 17which is projected through a slotted lug 18 on the block, said lug beingpositioned through a slot 19 in the standard.

The block 16 is made with ar gas passage 2O which is supplied with gasby a nipple 21, the latter projected through an opening 22 in the frontof the lire box. This opening is ordinarily provided to accommodate theshaking shaft or trunnion of the grate.

The top casting 9 is formedat its ends with relatively` large gasburners'23, having' removable perforated burner plates 24:, the latterpreferably located under the stove holes 25, so that a cooking utensilcan be convenientlylocated over the same.

Gas pipes 26 and 27 connect the two burners respectively with the gaspassage 2O and have cocks 28 and 29 respectively therein to control theflow of the gas to the burners.

The burner boX 10 has an inlet nipple 30 inits bottom connected bya pipe31 with the gas passage 2O and having a cock 32 therein. Y

This burner boX 10 is made with a forwardly extruded chamber 33 at itslower end having burner nozzles 34 in its top and other burner nozzles35 are provided in the upright wall of the box. The nozzles 34' and 35.direct the flame and the heat toward the water back 3 to rapidly heatthe same and thedraft over` the top of the vbox is .controlled by ahinged plate 36.v This plate may be given the desired angulardisposition according to the shape of the waterback and its draftdesired and I have` illustrated in Figs. 1 and 2, two different positions of this plate.

A convenient manner of securing the platek at its angle of adjustment isto provide a i slotted curved arm 37 on the plate and clamp the saine toone of the standards 7 by means of a bolt and wing nut 38.

The box 1G is preferably made with aref movable back plate 39 secured byscrews4), so that the box and nozzles can be eilectually cleaned out asoccasion may require.

Asemi-cylindrical screen 41 constituting a gas distributor, is locatedover the nipple 30 in chamber-33, and operates to distribute the gasthroughout the box, preventing an over supply at any one set of nozzles,and a partition strip 42 is secured above the screen and cooperates withthe screen in the performance of its functions.

l have illustrated in Fig. 7 a damper or draft controlling means whichcan be attached to the burner box and control the flow of air or inletof draft between the box 1() and the water back 3. This draft controlcomprises a plate 43 which is secured to the outer face of the chamber33 and which extends up to the bottom of the water back 3. A slidedamper 44 iswmounted on the plate 43 and this damper 44 and plate 43have registering openings 45 to permit the `air to pass through them andover the ltop of the chamber A partitionplate 46 is secured to plate 43,projects at right angles thereto and is positioned above the openings 45so that this plate 45 acts as a deflector to compel the air te passlaterally as far as de! sired to `give the necessary oxygen supply tothe several nozzles of the burner box to aid combustion.

1t will be noted particularly by reference to Fig. 7 that the burnernozzles 34 on top of the chamber 33 heat the bottom of the water back 3and hence, these burners give efficient results to quickly heat thewater. p

t will thus be noted that 1 provide a heater which can be placed inthelire box of a coal range to heat the water baclr and supply allnecessary heat for cooking purposes.

lhe device can be easily and quickly in` stalled and the pipes andcoupling block can be positioned at either end or either side of thedevice in accordance with the location of the fire box, whether it be atthe right or left hand end of the range, as the parts are made easilychangeable or reversible.

Various slight changes might be made in the general forniand arrangementof the parts described without departing from the invention, and hence Ido not limit myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the appended claims.
